<<As I understand it Gar are no good for eatin'>>
Ever eat whitefish-based artificial crab meat? It tastes very similar. You can also pickle the meat; since its not as hardy as meat from other fish the pickling gives it body. The trouble is gripping that darn notochord and yanking it through its neck hole. Some people make the mistake of using fillet knives on their armor, but tin snips cut through them in short order. I have only done it a couple of times because of the hard work to clear the notochord, but the ones I did were actually tasty. A gar that big would have been alot easier than the 2-pounders I did. Not much different than eating sturgeon.
I like large catfish like that, too. Very easy to steak out a fish that big.
